Which expression would be easier to simplify if you used associative property to change the grouping.
A. 4+(1.2+(-0.2))
B. 85+(120+80)
C. [-40+(60)]+52
D (2+3/7)+4/7
(I'll give brainliest for the correct and most accurate answer.)

Answers

Answer 1

Answer:

D. (2 + 3/7) + 4/7

Step-by-step explanation:

In B and C, the numbers involved in expressions are integers.

Hence, they can be easily added or subtracted.

In D, the numbers involved in expression are fractions which are not grouped together.

They can be added but by using associative property, it becomes much more easier.

That is, grouping fractions.

Answers

Z=6.5 because 118/2 is 59 and 13/2 is 6.5 hope I got it right and it helped

Answer:

[tex]z = 6.5[/tex]

Step-by-step explanation:

If we take a look at the problem, we are solving for z.

[tex]\frac{118}{13} = \frac{59}{z}[/tex]

To figure it out, we have to cross multiply. So we take [tex]118 * z[/tex] and [tex]59 * 13[/tex], which gives us [tex]118z =767\\[/tex]. Next, we divide both sides with 118.

[tex]\frac{118}{118}z=\frac{767}{118}\\ \\z = 6.5[/tex]

Then, we get 6.5 as our answer!

Hope this helped!

The Industrial Revolution began in Great Britain, a fast development ofsociety following the introduction of machines. The United States was slower than Great Britain to fully embrace the changes. Yet key technological developmentscaused a rapid growth in American urban areas.Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for their families as well as to sell. Theabundance caused food prices to fall.The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry. More people turned to work innorthern factories as a way to support their families. Thousands of immigrants to the United States also settled in or near port cities, looking for work. Even today,the need for work is a common reason people move to urban areas.As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildings for living and working. They needed ways to move around the city. We call this process urbanization,In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urban areas. The number of cities withmore than 10,000 people grew quickly over the next 40 years, especially in the Northeast and Midwest. By 1860, about 20 percent lived in cities. Philadelphia andNew York City were the most populated cities in 1860 and would soon reach one million residents.The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could not have grown soquickly. The trend quickened after 1860 and continued throughout the 21st century as well. By 2007, more Americans lived in or near cities than they did in ruralareas.Which sentence from the introduction paragraph serves as the author's thesis?
